The various fabricating units which go to make up the finishing machinery should be mounted in such order along the fabricating line as will permit each operation to be performed in proper sequence in accordance with the article of ware being produced, and the frame of the apparatus is constructed to permit interchanging of the said units as desired. If cups or analogous: ware which require turning and finishing and/or handles are being produced in one or more lines, this were is conveyed through the drier until in a leatherhard state and then transferred from the main drier to the supplemental drier or treating cham-- ber and turned and finished while undergoing transfer at G, Figure 34. The ware is inspected and transferred back to the main drier and conveyed therethrough until dry. In the case of plates and analogous ware which may not require turning, and/or handles and like appendages, this Ware completes the cycle through the main drier without interruption until dry, then passes out of the main drier and may be cleaned or otherwise treated at L, the bottoms finished at M, the

edges and surfaces smoothed at N, and finally treated or cleaned at Q.

As the trays bearing the molds with ware thereon progress along the lower main fabricating line, they pass over reciprocable and rotatable chucks 62 forming part of the mold-actuating units shown by Figures 1 to 7, inclusive. The complete assembly is mounted on a skeleton frame 63 which is adjustably secured on cross supports 63a, by screw bolts 63b, extending through enlarged openings, and centering dowels 630, the latter being removed in the event it is desired to shift the unit from its initially aligned position. The cross supports 63a are suitably adjustably secured to the base of the main frame 38 of the machine. The casting or frame 63 is provided with a bearing housing 63d for a spindle 64, see Figure 5, the lower extremity of which has secured thereon a collar 84a by means of a pin 8412, said collar supporting a thrust bearing assembly comprising a tapered collar 64c, bearing rollers 840', a saddle 64d and spring 64e, a cover 64 being adjustably threaded into the housing against which said spring abuts, so that the spindle moves upwardly against the tension of said spring and lowers" by gravity assisted by said s ring.

The spindle 64 is in spline-sliding engagement with a chuck spindle 620 on which the chuck 62 is secured by a screw 62c and dowel pin 62c2, reciprocation being imparted to the chuck 62 and spindle 620 by means of a cam 62d, mounted on a cross shaft 62c having bearing'in the side frame plates 38a of the main frame of the apparatus, said cam actuating a lever 62f, which is adjustably pivoted at one extremity. the pivoting assembly being supported from the frame 63, and at its opposite extremity pivotally secured to apitman 629, the pitman connecting with spindle 620 by means of a cross fork 62h, which is adjustably secured to said pitman by nuts 62f at its one extremity and forked into an annular groove in the spindle 620 at its opposite extremity. The pitman 62g projects through and is guided by extensions 62a of the frame 63, the upper end of said pitman having adjustably threaded therein a contact screw 62k, the function of which will later become apparent.

Rotation may be imparted to the spindle 64 in the unit illustrated in Figure 1 by means of cooperating friction gears 64g and 6412., the gear 64g being adjustably secured on the spindle 64 and the gear 647; splined for longitudinal sliding movement on a cross shaft 641, which is preferablycontinuously driven, this shaft having bearings at opposite extremities in the side frame plates or beams 38a.

The friction gears 64a and 6471. are brought into intermittent contact by a lever and brake assembly comprising a brake shoe 641 formed with studs for mounting the shoe for vertical movement on the frame 63, a bell-crank lever 64]: pivoted or fulcrumed in said frame, a connecting rod 64! adapted to be adjustably pivoted at one extremity in any one of a plurality of holes formed in said bell crank lever and at its opposite extremity adjustably secured by nuts 64m on a pitman 841i, and cam-contacting arms 640 and 64p which are also adjustably secured on the pitman 6411 by nuts 64q and 641'. These arms 640 and 64p are alternately raised and lowered by separate cams, now shown, which are adj ustably mounted on the shaft Me. The frame 63 is formed with guide brackets 64f for the pitman 641a.

To vary the speed of rotation of the chuck during reciprocation thereof, the splined friction gear 64h is provided with a grooved hub 64h, also splined on shaft 642', and a grooved cam 64712 is adjustably secured on shaft 62e, motion being transmitted from the came to said gear by a lever 64h3, which is adjustably pivotally supported at its upper extremity on a bracket extension 630 of the frame 63, said lever extending downwardly and adjacent cam 64h2 being provided with a pin 64114 working in the groove of said cam, and at grooved hub 64h by a link 64h5 and pin 64h6 working in the groove of said hub.

In, operation, the chuck-reciprocating cam 62d and brake cams being adjusted'to work in synits lower extremity said lever connects with the into contact with the continuously rotating gear 84h and imparting rotation to the chuck; and when the chuck is lowered, brake 641 is raised and thus contacts with gear 649 and raises the spindle 64, thereby moving gears 84g and 64h out of contact and stopping rotation of. the chuck.

To gradually accelerate and decelerate or vary the speed of rotation of the chuck durin reciprocation thereof, the drum cam 64M and lever 64h3 may be used to move the gear 64h relatively to gear 640. Ordinarily, however, the brake, if properly adjusted, will operate to effect gradual contact and release of the gears 64a and Mn and provide for smooth operation of the chuck 62.

In Figure 3 the chuck is adapted to be rotated through the medium of a segmental gear 65 formed integral with a lever 650, which is actuated by a cam 65b, adjustably secured on shaft 647', against the tension of a retracting spring 65c, the lever being adjustably pivoted in the frame .63, the segment 65 meshing with a pinion 65d adjustably secured on the spindle 64. The cam 65b is shown as being of symmetric contour but may be replaced by a cam contoured in accordance with the work involved, it being obvious that an irregular cam would impart intermittent rotation to the chuck, and the cam 62d may also be given an irregular contour to give the chuck a number of minor reciprocations. This form of chuck rotating means is of particular advantage where it is desired to synchronize the rotary time and motion of the chuck with cooperating fabricating units, and is used, for instance, when the chuck is to be rotated in reverse directions as in closing the partible undercut ware molds 59, as by adjusting the throw of lever 65a and/or substitution of a suitably contoured cam, the chuck 62 may be caused to rise and contact with and lower and release the molds in predetermined angular positions, and also impart a definite number of revolutions to the mold when elevating the latter clear of its tray. This chuck-rotating assembly may be applied at any point along the fabricating line in place of that illustrated in Figure 1, as the frames 63 are constructed to provide for interchangeability of parts.

The shaft 641', on which the continuouslydriven gears 64h are splined, and the cam shafts 62c are arranged so that they may be driven from the main drive shaft 44, or, as shown in Figure 34, the shafts 64f may be driven from an independently-driven shaft 66 and the shafts 62c from shaft 44, note Figure 34 and the reduced view,

Figure 7, the drive being transmitted by helical gears 61 and 61a, the gears 61 being adjustably secured on the shafts 66 and 44 and the gears 61a on the cross shafts 62c and 641'. The speed ofv rotation of shafts 62c and 641. may be independently varied along the fabricating line by simply changing the ratio of gears 61 and 61a. These latter gears are used at various points in tire entire apparatus, as will be noted in Figure 3 The shaft 66 is supported in bearing brackets 66a, which project at intervals from the main frame of the machine, said sh'aft being driven by a motor 66b, see Figure 34.

Super and sub-atmospheric pressure and other mediums may be applied to the molds through the chuck for various fabricating operations, the passages 62a and 62b extending down into the chuck spindle 620 as shown and opening out into annular registering air grooves 62a and 62b formed in a hood 10 having a working fit around said spindle and adlustably supported on the frame 63 by a thread rod 16a, hose nipples 62a! and HM being threaded into the hood Ill and communicating with said grooves. A further communicating passage opening out in the bottom of the chuck is provided by a bore H in the screw 62c, the interior of the spindle 62c being hollow, thus forming a chamber Na, and the hood 16 having a further groove 'llb in communication with said chamber, a hose nipple -Hc being threaded into 'the hood l0 and communicating with said groove; Where the passages 62a, 62b and H open out into the chuck 62, resilient sealing and cushioning pads 621 are adiustably threaded into said chuck.

Many of the fabricating tools and attachments are mounted on a standard form of carriage assembiy substantially similar to that illustrated in Figures 8 and 8A, for the purpose of giving them the desired movements relatively to the ware on which they are to perform.

The reference numeral 85 designates vertical guide and stop posts which are adjustably secured in and dependfrom one of the top plates 380 of the machine, a frame 85a shown as of rectangular shape being mounted to have a vertical sliding fit-on said posts, nuts 85?) being threaded on the lower extremities of said posts to adjustably limit the lowermost point of travel of said frame. The frame 85a is formed with a bracket 85c, which is bored to receive apivot bolt 85d, which is adjustably secured by nut85d, a lever 85e being pivoted at one extremity in said bolt and at its opposite extremity adjustably and pive otally supported from a post 85f,'which also depends from and is secured in the top plate'38c. This lever 85c is provided with a cam roller 85c adapted for contact with various types of frameactuating cams shaped in accordance with the work involved and which are mounted on one of the cross shafts 80a, or if the variable speed assembly is used, on the sleeve 68, these cams being shown in connection with the various attachments hereinafter described.

The lower portion of the frame 85a is formed with a dove-tail slot or groove in which a bar 859 is mounted to have a horizontal sliding fit, the

bar at the left as viewed in Figure 8 being formed mam cally and the bar as; laterally, the bar derivingits vertical movement from said frame. The

frame is provided with screws 851a and 850 adapted to be adjusted in contact with the posts 86 and frame 86a in the event the actuating cams are to be disconnected and the frame and bar set in rigid adjusted position.

An attachment and tool-mounting turret disk 86 is supported from the slide bar 850 by means of a hanger bracket 86a, said bracket being formed with projecting hub portions 86a and 86a2, see Figure 8A and is secured to the bar "85g by screws 86a3, see Figure 9, the disk 86 be- 1 ing rotatably mounted on the hub. 86a and preformed on the frame 85a, the one extremity of with a vertical guide bracket 85h having a cenin connection with the attachment.

The bar 85g is slotted at 85k, a pin 85k being secured in the frame 85a, a compression spring 85k2being mounted to abut at opposite ends, respectively,,against said pin and the bar 85g. The bar 85g is also provided with a screw bracket 851 in which a contact screw 85m is mounted, which serves to adjustably limit the movement of bar vented from lateral displacement by a ring 86ml. A shaft 86b extends through and has bearing in the projecting hubs of bracket 86a, this shaft functioning in a manner which will later become apparent. The disk, likethe feeder turret Bid, may be rotated intermittently in one direction or oscillated, the detents 8| g and 8H being housed, respectively, in a gear 860 and the bracket 86a and adapted to register in detent or latch notches Mg and spotting notches 8H formed in. one side of said disk 86, there being four of each of said notches in th present instance. The gear 86c is mounted to rotate free on the bracket hub 86a and the teeth 860' of said gear are in continual mesh with the teeth 86d of a rack 86d, the latter being slidably dove-tailedinto a groove formed in the bracket 86a, see Figure 8A, and terminating in a, T-head 86:12, see Figurev 9, which is formed with a track 86d3. The rack 8611 is actuated by a bell-crank lever 86e, which is fulcrummed at 86e' on a bracket extension 86e2 said lever 86c being provided with a pin 86e3 which has a sliding lit in the groove or track 86d3, while the opposite extremity of said lever has pivoted thereto a connecting rod 86} which extends through a guide bracket 86]3 and terminates in a T-head 86 formed with a groove or track-86ft, said T-head cooperating with a lever 86g pivotally supported at its upper extremity from a post 86h, which is secured in one of the top frame plates 38c, and at its lower extremity said lever is provided with a pin 86g' having a sliding in the groove or track 86f! of T-llead 86f. Lever 86a is provided with a cam roller 86g! adapted to contact with a suitably shaped cam to be mounted on shaft 86a, these cams also being generally shown with the respective'attacm ments hereinafter described. A retracting spring 86114 is secured at opposite extremities, respectively, to the T-head 86d2 and the bar 859.

A screw 86! is shown as threaded in the bracket 86a, see Figure 8A, this screw being adjusted 65g in one direction independently of its cam travel or reverse'movement. The screw bracket to conform to the positive direction of movement of the cam lever 852'.

It will be seen that when levers 85c and 855 are oscillated, the frame85a, reciprocates vertiagainst the turret disk 86 when it is desired to maintain said disk'stationary with said bracket. A screw 861 is also shown threaded in the hub 86a! of. bracket 86a, and this screw maybe adjusted against the shaft 86b when it is desired to maintain the latter stationary with said'bracket.

he disk 86 is provided with a plurality of holes 86k for attaching various fabricating tools and attachments, such as shaping tools, turning" and finishing tools and transfer chucks, which will 'be described in connection with each respectiv fabricating operation.

The shaft 861) may be driven by either a positive or friction drive, both forms of drive being shown in Figures 9 and 10 for the purposes of illustration.

A bevel ear 81, formed with a hub 81' is shown as adjusts, ly secured on the shaft 86b, this gear stub shaft 81a which has bearing in the projecting extremity of abracket arm 86a5 formed as part of the bracket 88a.' A bracket 81b is adjustably supported by a post 81b from one of the top frame plates 38c and extends down and at its lower extremity is formed with a foot 81b2, a stub shaft 810 having bearing in said foot, this shaft forming part of a flexible coupling comprising a sleeve 81c and longitudinally grooved shaft 8102 in spline-sliding engagement with said sleeve, the lower extremity of shaft 81c! being coupled for universal movement with the stub shaft 81a on which gear 81a is secured. The stub shaft 810 of the flexible coupling has adjustably secured thereon a pinion gear 81d, which may be replaced by a friction gear 8111', see Figure 10, when a non-positive, intermittent or continuous high-speed drive is desired. If pinion 81d is used, the drive is effected by means of a segmental gear 81e formed on a lever 81c, which is adjustably pivotally mounted on the bracket 81b and provided with a cam roller -81e2 adapted to' contact with a cam to be mounted on shaft 80a or sleeve 68 and which may be given various contours in accordance with the rotation desired for shaft 86b. The lever 81c may be retracted by a spring 81];

If the friction or'non-positive drive is desired,

I the friction gear 81d may be substituted for pinion 81d and a cooperating friction gear 81 splined or mounted for longitudinal sliding movement on shaft 80a or sleeve 68, the latter gear being formed with a hub having an annular groove 819' formed therein. A grooved cam 8111, adjustably mounted on shaft 88a, transmits longitudinal sliding movement to friction gear 819 by means of a pin 81i, slide rod 811'2 and pin 81:, the pins 812 and 812" being adjustably secured on slide rod 811! which in turn is mounted to slide longitudinally in adjustable supporting brackets 817' which extend upwardly and are secured in one of the frame plates 38c.

If the rotation of shaft 861) is to be alternately reversed, the drum cam 81h may be used, this cam movement causing the friction gear 819 to move across the face of gear 81d, and when the gear 819 passes over the vertical axis of gear 81d, the rotation of said gear will be halted and then reversed, thus reversing the drive on said shaft The jack shaft 681 of the change-speed assembly is shown as mounted and having gearing in hanger brackets 81]" which are also adjustably supported by posts 817'2 from one of the frame plates 38c.

Some of the fabricating attachments are shown mounted directly on the turret disk 86 w ile others are shown, mounted on a turret 88, see Figure 24, which is secured to the disk 86 by screws 88a. This turret may be rotated in accordance with the particular attachments in use. If there Y are four attachments on the turret and all are being used in succession, the lever 86g may be actuated by a cam.

Super and sub-atmosphere, electricity and other fluid mediums may be communicated to the various fabricating attachments that mav' be applied to the turret disk 86, see Figures 8A and 34.

For super and sub-atmosphere, liquids and analogous fluids, the bracket 86 is bored to provide passages or ducts 13c and 13), which lead through the hub 86a and register with passages 13c and 13]" formed in the turret 88, these lat- 8 ter passages terminatingin annular'grooves or chambers 18e2 and 13,12. The fragment of the turret 88 shown in Figure 831:; provided with a rotating spindle or post which is formed with passages 13e3 and 1M3 which register at one extremity with said chambers and at their opposite extremities terminate at the point of application. Hose nipples 13e4 and 13M -aresecured in the bracket 86a, see Figure 8A for connection 0f the air'or fluid lines leading to the control valves 12. i

To supply the various attachments'that may be applied to the turret 88 or disk 86 with electric current, the bracket arm 86115 may be formed with a projection on which are secured brushes 81k and 811, Figure 8b, which are adapted to contact with suitably insulated commutator rings 81k and 811' secured in the adjacent side of the disk 85, said rings being connected with another 20 set of commutator rings 81M and 8112 secured on the periphery of said disk and which in turn transmit the current to the attachmentthrough contacts or rings 81k3 and 8113 secured in the attachment, 9, fragment of the latter being shown in Figure 83. v

, With reference to the diagrammatic illustration in Figure 34, at the left of the drier the cups, which may have then reached a partially dry or leather hard condition, are shown as being transferred from the forming molds in the main drier to the upper treating chamber and turned and finished during the'process of transfer. However, means are provided for transferring any particular shaped article of ware, the chucks for gripping the ware being preferably mounted on one of the turrets 88, and are generally designated by the reference numeral 91, see for example, Figures 23 and 24. These ware-gripping chucks are so constructed that were which may be in a leather-hard state as well as delicate and fragile ware may be transferred without distortion, marring or breakage, said chucks being shown in detail in Figures 11 to 14 inclusive.-

The transfer movements of the chucks 91 are governed by the carriage assembly illustrated in Figures 8 and 9, the method of mounting said chucks on the turret 88 being shown in Figures 23 and 24. Each chuck is preferably provided with a stem 91a and operates to grip the ware through the medium of suband/0r super-atmosphere, which maybe conducted to the chuck by means of the spider attachment shown in detail in Figure 16. The shaft 8612, Figures 8 and 9, is formed with a longitudinal bore in which a tube 81b, Figure 16, is inserted, the one extremity of said tube being provided with a hose nipple 91b2, see Figures 24 and 26, and at its opposite extremity said tube projects through the shaft 86b. This tube has a free fit in said bore, as the shaft 86b rotates independently thereof, and the spider is formed with a hub 91b3 which is rotatably mounted on the projecting extremity of said tube', see Figure 16. The tube 81b is closed or formed solid at its one extremity and provided with a port 91b4, and the hub 91123 is formed with a plurality (four in the present instance) of radial bores 91b5 in which tubular arms 91b6 are secured, said bores being adapted to register with the port 91b4 as the spider rotates on the tube 91b. The chuck stems 910. are also formed with longitudinal bores 91a and .the tubular arms 91b6 telescope and have a rotatable working fit therein, said stems extending through and being in longitudinal spline-sliding engagement with the gears 89a which are in mesh with the ring gear 89, previously described. Collars 81b1 and 91b8, see Figure 23, are adiustably secured on the chuck stems 91a, by means of which the stems may have an adjustably limited range of longitudinal sliding movement in the gears 8921 or be held longitudinally rigid therewith.

Figure 11 illustrates a transfer chuck adapted to grip the ware from the bottom, said chuck comprising a body block 910, which is interiorly bored and threaded to receive the stem 91a, the block 910 being adjustably secured on said stem by a nut 91d. The bottom surface of the block is recessed or formed with an annular cavity 91c, the resulting flange being shaped to center on the bottom bead of the ware as at 91c, a plurality of vacuum cups or nipples 91 being adiustably threaded in the block 910, th cups preferably being three in number and spaced angularly, said block being formed with conduits or passages 91:12 which establish communication between the bore 91a in stem 91a and the vacuum cups of nip pies 91f.

It will be noted that this form of chuck leaves the greater surface portion of the were free for turning and finishing operations, an advantage which will later become more apparent, and further, that the angular spacing of the nipples 91f provides a three point were surface contact which will always be equal at all points regardless of.

whether the gripping surface of the ware is of regular or irregular contour.

The chuck illustrated in Figure 12 is particularly adapted for gripping the interior of deep ware and may be operated by either sub or super atmosphere. Simply for the purposes of illustration, parts are shown in this chuck which would render the chuck operative, if used alone, or in other words, a number of modifications in structure are included in the same figure to conserve space.

The block 910 in this instance has secured on the top surface thereof an annular flexible sealing valver91g, which functions to seal the space between the chuck and ware when sub-atmosphere is used as the gripping medium. The passage 91a2 in this instance branches off at various points as at 91113, and where these passages terminate, cushioning plugs 9172., which may be of soft rubber, are adjustably secured therein to ensure against marring and distortion of the were during transfer and a number of these plugs may be solid to selectively close said passages. A guard or stop member 91i, which centers on and contacts with the mold is adjustably secured on the stem 91a, by a nut 91i, to adjustably limit the approach of the grip head to the ware, said guard being vented at 912'2.

The block 916: in shown as being formed with an annular recess to receive a flexible or expansible tube 917' (which may be in the form of a series of bulbs), formed with a nipple portion which fits in the passages 9M3. This tube may function as the gripping means through the application of air under pressure and also serve as a further centering and cushioning means for the chuck relatively to the ware. It will be seen that the expanding force will be applied equally in all directions by adopting this construction.

A further method of providing a grip means is to form a series of radial bores, preferably three, in the block 910, which meet or converge at the central passage 91a2, gripping pistons 91k being mounted to have a sliding fit i saidbores, cushioning pads 9110 being secured on the ends of said pistons. These pistons may be expanded by air under pressure or super atmosphere and retracted by sub-atmospheric pressure or by springs 81M, the latter being housed in said pistons and secured at one extremity thereto. The abutting end of each piston may be formed with a bore segment, thus providing a complete bore which registers with the passage 91112.

It will also be apparent that in this type of grip means the expanding force is applied equally in all directions.

Figure 13 illustrates a chuck adapted to grip the exterior of deep ware. the expansible tube 811 being utilized as the grip member as in Figure 12. It will be noted that the block 910 is vented the ware.

The assembly is preferably mounted on the turret 88, the stem, 91a in this instance being formed with an enlarged rounded head and the body block 910 is socketed and clamped on said head by means of adjustable pressure plates 91d. The stem for this type of chuck serves as a bearing block or bracket 91! shown in section, which may be formed on the turret 88, said stem being formed with an annular end flange 91m, to prevent lateral displacement toward the right as viewed in Figure 14,

At an intermediate point, the stem or shaft 91a is formed with a pinion 911i adapted to mesh with a depressible rack 8111., which is formed with a cam-contact hump 91112 and a pin or leg 91n3, the latter being encircled by a spring 91114 and having a sliding fit in a bracket 91125, a nut 91126, which is threaded on the one extremity of said leg 91113, serving to adjustably limit the travel of the rack 9112' in one direction. A cam 91n1 is shown as adiustably secured on the shaft 8% for depressing rack 9111'.

Suband/or super-atmosphere may be applied through either one or both of the passages 13ee'-e2 or 13j-f-f2, see Figures 8A and 8B,.

In operation, cam 9111.1 depresses rack 9112. in mesh with pinion 9172, turning stem or shaft 91a and the chuck secured thereon, and this turning operation may be initiated at any desired point of the transfer operation by adjusting the actuating cam for lever 81c, Figures 8A and 8B, which is not shown but may be shaped substantially similar to the cam 91111 to permit change of phase while in operation, or by adjusting cam 91111 on shaft 86b. It will thus be apparent that the position of the chuck may be changed to conform to the points of pick-up and deposit of the were while moving from one point to the other.

Figure 15 illustrates a modified form of chuck for shallow ware, the guard 91i in this instance being secured to the block 910 and the stem 91a being formed with a flanged or enlarged head 91:14 which has a loose mounting in a recessed equalizing, contact with the-gripping surface'oi the ware.

As the transfer movements of the chucks are.

overned by the carriage assembly illustrated in Figures 8 and 9, wherein, the throw of the various levers may be adjusted while in operation, the

'the transfer operations, and this facility of control of the chucks is of. particular advantage in the automatic turning and finishing of the ware,

which willnow be described.

Ware may be taken from and deposited on a continuously-moving conveyor or other supp rt by timing the movement of the slide bar 859 so that it will travel with the moving ware conveyor or support while the chuck is operating to grip and release theware.

In the apparatus as arranged in Figure 34, the turning and finishing assembly is mounted to operate on the ware as it is being transferred from the lower main drier to the upper treating chamber in a manner to be described, but it will be understood that the turning and finishing as semblies may be mounted in cooperative relationship with the carriage assembly carrying the transfer chucks at any point along the fabricating line where desired.

Referring to Figures 17, 18, 19, the assembly is adapted to be adjustably supported from any of the frame plates 3 8c by posts 98. The tools used in the turning and finishing operations are of different types in accordance with work involved, the cutting tool in Figure 1'7 being indicated at 98c and the burnishing and finishing topl at 98b, each of said tools as here shown being adjustably secured in the armature shaft of a motor 98a and 98b and independently driven, th motors being supported by blocks 980, which are adjustably secured to a bracket 980' by a screw 9802, said bracket in turn being adjustably secured to supporting posts or shafts 98d by a screw 98c3, see Figure 19. By loosening screw 9802, block fltcmay be adjusted angularly relatively to bracket 98c, thereby adjusting the tool, and by loosening screws 9803 the bracket 980' may be adjusted angularl relatively to posts 98d and also vertically on said posts, thereby similarly adjusting the tool. It will thus be seen that each tool is universally adjustable so that the tools may work at varying angles relatively to'the ware.

The posts 98d are secured in upper and lower arms 98d and 98:12 which are mounted to occillate or yield in a horizontal plane in bearing collars 98d3, the latter being adjustably secured on the main supporting posts 98.

A bracket 98c is secured on the lower ends of the posts 98, see Figure 19, said bracket being formed with an extension 98a and a lug or car "e2, retraction springs 98014 being secured at opposite extremities, respectively, to said lug and the lower arms, which move outwardly against the tension of said springs, and to adjustably limit the inward movement or approach of said arms toward one another, abutment screws 98125 and 96116 are threaded through said lug 98c! and may be adjusted relatively to said arms,

The tools 98a and 98b are accurately guided by a pattern cam 98f, which is mounted on the transfer chuck stem 91a and may be secured thereto by screw 98)" and rotate with the chuck and ware, or rotated free on said tem at varying speeds relatively to the chuck and ware, the hub on the 'cam 88! being adapted to receive change speed ar 68b, gear 68a being secured on stem 91a and the jack shaft 68 for gears 68c and 68d having bearing in the turret 88. A bearing collar 98! is removably and adjustably secured on stem 91a below cam GM for supporting the cam when loosened for free rotation on said stem.

Tracers 9813 are mounted for universal adjustment similar to the motor and tool assembly above described on the posts 98d, these tracers being adapted to follow the contour and design or pattern on cam 98] as the latter rotates. and as the tracers -are mounted rigidly relatively to the tools 98a and 98b, this motion will be translated to said tools.

The bracket extension 98c has mounted thereon a bottom turning and finishing tool 98g which is centered relatively to the axis of the transfer chuck when the latter is in operative position between the tools and tracers, so that the rotating ware may be lowered onto this tool at the beginning or completion of the turning and finishing operation, in this instance, at the beginning of the work.

A chip and dust receiving housing 98h is also mounted on the extension around'and beneath the bottom tool 989, the dust particles and chips resulting from the turning and finishing operations falling therein and are preferably removed therefrom by' suction, a hose nipple 9872. being attached to said housing for the vacuum hose.

These cams are preferably mounted as in one of the cross shafts 80a, so that the phase of motion of the partsprimarily actuated by said cams may be under ready control while in operation and while the driving connection subsists.

The cam for lever 85e or the vertical motion,

lever is designated 981, the cam for lever 851', or the slide bar lever, which carries the turret 88 and transfer chuck together with the pattern cam 98 and various gears and appurtenant parts is designated 989', the cam for lever 81g or the lever which turns the turret after each turning and finishing operation is designated at 98k, and the cam for. segment lever 81c which drives shaft 86b and rotates the pattern cam and transfer chuck with the ware thereon is designated 98!.

In the position shown in Figures 17, 18 and 19, the ware is moving in toward the tools, which will be moved further apart to initially clear the ware by the pattern cam moving therebetween. When the ware shall have reached an intermediate actuated by cam SM and the ware rotated, lever c lowering and rotating ware onto the bottom tool 98g, dwelling at short period, at which time the side tools 98a and 98b are outof contact with the ware. Cam 982 then raises lever 85c and the rotating ware moves upwardly and the tools 98a and 98b, which are guided by tracers 98]3, move into contact with the vertically moving rotating ware to perform their respective functions, after which the turret is given a partial turn to deposit the ware in a handle mold as illustrated in Figure 34 and bring another chuck and pattern cam into operative position, or the same chuck may be oscillated back to repeat the operation, depending upon the position of the latch Bl g in the disk 88, Figure 8A.

' finishing assembly particularly adapted for plain ware or ware having a regular surface contour. In this instance, the turning and finishing tools are designated at 98112 and 98b2 and are primarily driven from a vertical shaft 98m, see Figure 22 which has bearing in the bracket 98c, and may be driven from any suitable source, as for instance, one of the shafts 88a, the drive being transmitted to the posts or shafts 9811 on which the tools are secured by means of a gear. 98m, which is secured on shaft 98m, idler gears 981112 and 98111.3 which transmit the drive to gears 981114 and 981125, these latter gears being secured on vertical shafts 98m6 and 98ml, also having bearing in bracket 98c. The posts or shafts 98d in this instance are mounted to rotate and extend through and have bearing in the lower arms 98d2, and the posts or shafts 98d and the shafts 98m8 and 98111.! are provided with sprocket gears and connected by sprocket chains 98m8 and 98m9 or analogous positive flexible drive connection.

In addition to the bottom tool 989 shown in Figure 17, a bottom burnisher 98g is provided in this instance, said tools being secured on jack shafts 9892 and 98g3 which extend through and have bearing in a bracket extension of the arms 98d2, the lower' -extremity of each shaft having secured thereon gears 98914 and 98g5 which are adapted to mesh, the drive being applied to gear 9895 by means of gears 9896 and 9891 which are secured on the posts or shafts 98d, see Figure 21.

The pattern cam in this instance is in the form of a profile disk 9W4, each shaft 98d having rotatably mounted thereon rollers 981 adapted to follow the contour of the profile disk 9814 during the turning and finishing or burnishing operations.

Figure 31 illustrates the cams for the carriage assembly, Figures 8 and 9 which are indicated by 981", 981", 98k and 981.

It will be noted from the contour of these cams that the ware first moves adjacent the tool 92a2 and over the bottom tool 98g, is then lowered and dwells, both the ware and tools being rotated, the

ware then elevating slightly to clear the tools and moving over adjacent tool 98112 and over bottom tool 989 and again lowers and dwells for the burnishing operation, after which the frame 85 is raised and the slide bar 85g retracted and the ware clears the burnishing tools and the turret 88 is given a partial turn as described in connection with Figures 1'7, 18 and 19.

This assembly is shown in operation in the apparatus at G.

Figures 23 and 24 illustrate an assembly particularly adapted for swabbing and edge-finishing were. This assembly is shown as mounted at the lower left extremity of Figure 34 to operate on the ware as it leaves the drier, the ware being transferred from the molds carried by the chucks 62 to .a ware conveyor. which is driven in s'ynchronism with the conveyer 40 as will hereinafter be described, the ware being finished and swabbed while undergoing transfer. 1

Referring to Figures 23 and 24, it will be noted that the transfer chuck in the position shown is about to rotate a plate in contact with an edgeflnishing tool, above and below and slightly to one side of which are mounted swabbing pads. This swabbing and edge finishing assembly is supported from one of the top frame plates 380 by an angle-bracket 98m"), which in turn has secured thereto an angle bracket 98ml I, the latter serving to support and stabilizethe upper extremity of a vertical shaft 98m, which is driven by means of bevel gears 9811113 and 98m, respectively secured on the shafts 98ml2 and a. The lower extremity of shaft 98ml2 extends through the bracket 98m) and has adjustably secured thereon a motion plate 98ml5, which coacts with a Geneva gear 98ml8 secured on a counter shaft 98m, which extends through and has bearing in the bracket 98ml8.

A turret head or bracket 987i is secured on the counter shaft 98ml 1, and to this bracket a plurality of swabbing members and edge finishing tools are adjustably secured, the members which are visible in Figures 23 and 24 being indicated at 9811', 98n", 98n2, and 98113, and the tools at 98114, 98125 and 98n6.

Each swabbing member is formed with ducts and faced with felt, sponge, or analogous absorbent material which is supplied with a suitable fluid from a chamber 980 formed in each member, the fluid being supplied to said chambers through ducts 980, which are formed in the shaft 9811111, and have connected thereto hose nipples for attachment of hose or analogous members 9802 which connect with valved hose nipples 9803 secured in the pad members 98n-n3, the shaft 98ml! being broken at an intermediate point to show said ducts, see Figure 24. At thevupper extremity of shaft 98ml'l, the ducts 980' terminate in annular chambers in a manner similar to the ducts 'I3e3 and 1313, Figure 8B, said ducts 980' being supplied with the required fluid through hose or analogous flexible members 9804, which preferably lead to the control valves and then to a source of supply.

Figure 32 illustrates a set of cams for use with the carriage assembly, Figures 8 and 9, when the transfer chucks are operating to bring the ware into operative adjacency to the swabbing and edge finishing assembly first described.

lhe vertical frame cam'for lever a is designated by 9822, the horizontal slide-bar cam for lever 851' by 9812, the turret cam for lever 969 by 98702 and segment cam for lever Me by 9812.

In the position shown in Figures 23 and 24, the plate has been gripped and raised from one of the chucks 82 and is just beginning its movement past and in contact with the edge-finishing tool 98114, see Figure 24, the ware moving toward the left as viewed in Figure 23 and away from the observer as viewed in Figure 24. Cam 9812 is about to actuate segment lever 81c and rotate the ware when in contact with said tool. After the ware has been rotated in contact with tool 98124, it moves farther away from the left, or toward the observer in Figure 24, and is lowered in contact with the swabbing pad 981: while still rotating, see contour of cams 9812 and 9812, and then elevated into contact with swabbing pad 9812.". Rotation then ceases and the ware is moved again toward the left and lowered onto a ware conveyor, the plates in this instance, being stacked on said conveyor, which is intermittently driven in synchronism with the transfer operation, the plate chuck stem 91a being in splinesliding engagement with gear 89a and telescoped over the tubular arms 91126 to permit this stacking operation.

The chuck then elevates and moves back and cam 98702 acts on lever 889 to partially rotate turret 88 and bring another transfer chuck into poturning and finishing tool and pattern cam, the

cam being designated by 98j6 and the tool by 98ab, the latter being independently driven by one of the motors 98a, the motor and tool assembly being adjustably mounted as in Figure 17, but in this instance, is secured on the post 98. The pattern cam 98f6 is also adjustably secured on the post 98, only one of which is required in this instance, and has a working surface contour in accordance with the shape of the ware.

The tool is shown enlarged in Figure 27 and has a beveled cutting edge or surface which acts or turns while the ware is rotating in one direction and finishes and burnishes while the ware is rotating in the opposite direction, see contour of cams 982'3 and 9813, Figure 23. Cam 9873 for the horizontal slide bar has a positive action toward the right as viewed in Figure 8, being reversed in this instance. The turret cam for lever 86g is designated at 98%. The bottom tool 98g operated substantially as in Figures 17 and 19.

In Figure 28, a tool 98:13 adapted to turn and finish the bottom of shallow ware while on the forming molds 53 is illustrated, said tool being adjustably secured on one of the transfer chuck stems 97a and is preferably mounted to operate on the ware prior to the ware turning and finishing assemblies previously described.

Figure 29 illustrates a tool 98:14 for finishing the interior of deep ware which is mounted similarly to the tool 98a3.

When using these bottom and interior finishing tools, a suction action may be set up through the chuck 62 and mold 53 to hold the ware in stable position on the mold. In Figure 29 the chip dust and other particles may be withdrawn from the ware by suction set up through the bore 98a in the chuck stem 91a, and this course may be also adopted with the bottom tool 98a3 or the housing 98h used in conjunction therewith.

The cams for these tools need only be the usual oval-shaped cams and are not shown.
